Wiehl and Henry get their new series off to a breathless start: on a cellphone, recently widowed prosecutor Mia Quinn, protagonist of the series, overhears her friend and colleague Colleen Miller being shot. Narrator Eleni Pappageorge channels Quinn’s intensity, but uses skillful pacing and tone rather than frantic vocals to convey the novel’s swiftly unfolding events. The authors have created an appealing lead in the still-grieving Mia, who is a bit overwhelmed by the responsibilities of single parenthood and leading an investigation into her friend’s murder. Equally appealing is Quinn’s partner, homicide detective Charlie Carlson, whose unconventional methods Quinn doesn’t trust. Pappageorge crisply presents the twists and turns of plot, while using subtle touches to suggest the characters’ moods. A Thomas Nelson hardcover. (March)
